ST. LOUIS - Marian Hossa kept his eye on the bouncing puck, all the way to the winning goal.

Hossa scored on a break-in at 19 seconds of overtime, capitalizing on a defensive mistake, in the Atlanta Thrashers' 3-2 victory over the St. Louis Blues on Sunday night.

'I saw their defenseman had trouble handling it,' Hossa said. 'It was just a lucky takeaway from him, and I just had to shoot it.'

Ilya Kovalchuk scored his NHL-leading 29th goal for the Thrashers, who have won four in a row in a six-day span.

'It would have been easy for us to roll over,' coach Don Waddell said. 'We could have been very satisfied with the weekend, but you could see the energy.'

Hossa swept in alone on goalie Manny Legace after Jay McKee fumbled the puck in the air and then lost control after Eric Perrin flipped it into the St. Louis zone. McKee said he was trying to swat the puck out of the slot to fellow defenseman Barret Jackman.

'That's not a puck you want to control with a guy like Hossa bearing down on you,' McKee said. 'Just when the puck hit the ice, it was a tough bounce and it's unfortunate in a game that we battled for ends that way.'

The Thrashers beat Montreal by the same score in a shootout on Saturday, and their winning streak comes after losing their previous four games. They won in St. Louis for the first time in franchise history.
